SELFCLOSlNG FAUCET.

PECIFCATON forming part of Letters Patent No. 340,329, dated April 20,1886.

Application filed January 21, i886. Serial No. llhlll. (No model.)

To @ZZ zij/"tom it may concern:

Be it known that I, HENRY B. LEACH, of Boston, in the county of Suffolkand State of Massachusetts, have invented new and useful ImprovementsinSelf-Closing Faucets, of which the following is a specification.

In the accompanying drawings, iu which similar letters of referenceindicate like parts, Figure l is a vertical section of a faucetembodying myinvention. Fig-2 is an elevation of parts of the easing,diaphragm, valvestem, and one of the rollers, the cap having beenremoved. Fig. 3 is a vertical section taken on a line at right angles tothe line of thc section in Fig. 1. Fig. 4. is a plan view with the capremoved. Fig. 5 is a plan view of the uuder side of the cap. Fig. 6 is aperspective View of one of the rollers. Fig. 7 is a view of thediaphragm provided with a slight modification. Fig. Sis a verticalsection showing further modifications. Fig. 9 is an edge view of one ofthe rollers. Fig. 10 is a sectional detail view showing a change in theshape of the rollers.

Ais thebody or casing of the faucet, provided with the nozzle A andinlet-tube A.

B is the cap, held in position 011 the casing by the screw b and washerc, the latter encircling and the former screwing into the stem C, whichpasses up through said cap. The valve-stein C is provided with the valveD, packed at D', the packing D, and the spring E.

F is the handle integral with the cap B.

H is a diaphragm bored centrally to allow the passage of the stem C,screwed into the casing A, and provided with shoulders H', which rest onthe upper edge of the casing within the cap.

I is au annular .stop for limiting the motion of the valve-stem. Theupper surface of /the diaphragm l-I is provided with the double inclinesh-that is to say, the circular path or track surrounding the valve-stemhas four in clines, preferably straight, as shown in Fig. 2,

,.biit, if desired, concave, as shown in Fig. 7,

the two apexes h being opposite cach other, and the two lowest points,Il, being opposite each other. The under side of the cap, which isopposite and over the diaphragm, is provided with double inclines 7c,exactly similar tothe double i nelines 7l, so constructed and arrangedthat the apexes 7c are exactly opposite the apexes h, and the points ofgreatest depressiomt, are exactly opposite the lowest points, h.

L L are rollers placed freely between the two sets of inclines andwithin the shell of the cap B. rllhese rollers may be of any desiredshape, provided of course that they are round. In Figs. 2, 3, 6, and 9they are of convex disk shape, in Fig. 10 they are flat disks, while inFig. 8 they are spherical or balls. \Vhen the handle F isturned andpartial rotation imparted tothe cap, and hence to the inclines on theunder side thereof, the rollers roll up the inclines h onthe diaphragmand the cap is lifted, thus raising the valvestem and allowing thewater-'t0 pass through the faucet. The

pressure of the spring E draws down the valvestem when the handle isreleased, and closes the faucet in the ordinary-manner, the rollersrolling back from the apeXes of the inclines to thelowest pointsthereof.

It will be observed that the rollers L, whether of the -shape shown inFig. 6, 8, or 10, are rollers in the strict sense of the term, and notwheels, as they travel on their peripheries, but do not rotate ontheiraXes.

If desired, the path of the rollers grooved out, as at P, Figs. 8 andl0.

The eifect of the rollers placed between the reverse inclines is toreduce the friction when the valvestem is moved to a minimum, so thatthe moving parts are always operative without the aid of a lubricant.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In aself-closing faucet, the combination, with the reverse inclinesor sets of inclines placed opposite each other, one of which inclines orsets of inclines is capable of partial rotation, of one or moreintermediate free rollers, substantially as and for the purpose setforth.

2. The combination of the rotary cap B, provided on its underside withacurviliuear track, the stationary diaphragm H, supported by the body ofthe faucet, and provided on its upper may be surface with a curvilineartrack, said tracks having their similarly-formed points of elevation anddepression located opposite to each IOO other, the free rollers L,placed between the tracks, the valve-stem C, aud the spring "E, allarranged to operate substantial] y as shown and described.

3. The combination of the cap B, provided on its under side With one ormore uclines, k, the diaphragm H, supported by the body of the faucet,aud provided on its upper surface with one or more inelines, h, and oneor more free rollers, L, placed between the iuclines ou the cap and theiuclines on the diaphragm, substantially as and for the purpose setforth.

4. The combination 0f the cap B, provided on its under side with thedouble iuelines k,

the diaphragm H, supported by the body of r 5 the diaphragm,substantially as and for the 2o purpose Set forth.
